- DriverHostActor.StopChild removes the driver's _lastReprovisionUtc stamp
(and its deferred-reprovision timer): the map grew per removed id and a
re-added driver inherited a backoff it never earned (02/L2).
- Stale now registers explicit drops for AttributeValueBatchPublished,
AttributeAlarmPublished, ArtifactForApply and ApplyWedged instead of
letting them hit Unhandled (02/H5).
- DbHealthProbeActor runs its SELECT on the thread pool and pipes the
outcome back (single-flight), with a 2 s command timeout on relational
providers, so a hung SQL Server no longer pins the actor thread and the
cached GetStatus answer stays reachable (02/P7).
- TelemetryLocalHub eviction tombstones are timestamped and swept past a
10 min TTL on the next Evict; a TimeProvider ctor is the test seam (02/L4).
- Tests: ValuePublishes.Single helper replaces the per-value
AttributeValuePublished in CalculationDependencyFlowTests (02/U4, test
half; the production receive is owned by Lane E).
- R05/8 audit: PollGroupEngine.Unsubscribe has no production caller; every
driver already uses UnsubscribeAsync (no change).

Clears CommentChecker findings in src/ (3,280 -> 209, the remainder being false
positives like PLC-5/IEEE-754/M0.0) by adding missing summaries/params/returns,
normalising inheritdoc usage, and removing Gitea/review tracking IDs while keeping
the rationale they annotated. Comment-only: comment-stripped sources are identical
to the parent commit.
DriverHostActor.StopChild released the tracker (Invalidate) and evicted the hub synchronously, but
Context.Stop is asynchronous: the stopping child's in-flight SubscribeBulk completed through its
capability invoker AFTER the release, and its RecordCallStart/RecordSuccess/RecordCallComplete
re-created the tracker entry, which DriverResilienceStatusPublisherService then re-emitted every tick
forever. Confirmed with a temporary stack capture in the tracker (removed): every post-Release write
came from DriverInstanceActor.HandleSubscribeAsync -> CapabilityInvoker.ExecuteAsync; the test failed
whenever it landed before the second publisher tick.
- DriverResilienceStatusTracker.Retire (Release) drops the id's snapshots and ignores every later
Record* for it; one guarded write path re-checks after the upsert so a write racing Retire cannot
survive it. Reinstate (called by DriverCapabilityInvokerFactory.Create) lifts it, so the same id
re-added in a later deployment records again.
- TelemetryLocalHub.Evict now also holds the id (late Health/Resilience dropped, neither cached nor
fanned out); ITelemetryLocalHub.Readmit (default no-op), called at the top of SpawnChild, lifts it.
- The removal test is now deterministic: an invoker decorator holds the child's subscribe inside the
real invoker's bracket across the removal and signals when its late writes are done (positive
control) — red 5/5 without the fix, green 20/20 with it. New unit tests for the tracker guard
(incl. a Retire race), the factory Release/Create pair, the hub hold/readmit, and a re-add-same-id
host test.
